  1. 1. Reconfigurable Intelligent Surfaces : Optimal Positioning and Coverage Improvement

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Noé Bernadas i Busquets; [2023]
    Nyckelord :6G; Reconfigurable Intelligent Surfaces; Wireless Communications; Coverage; 6G; omkonfigurerbara intelligenta ytor; trådlös kommunikation; täckning;

    Sammanfattning : Med framväxten av framtida mobilgenerationer bortom 5G, studeras nya teknologier för att tillgodose de förväntade kraven för framtida tjänster som Ultra-Reliable Low Latency Communications (URLLC) eller Virtual Reality. Bland dessa teknologier uppstår Reconfigurable Intelligent Surfaces (RIS) som en av de mest lovande på grund av deras förmåga att förbättra kanalen samtidigt som de bara ökar nätverkets energiförbrukning måttligt.

  3. 2. Cell Tower Localization using crowdsourced measurments

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carlos Escandón Álvarez; [2023]
    Nyckelord :Cell Tower Geolocation; Crowdsourced Measurements; Positioning; Machine Learning; Neural Networks;

    Sammanfattning : This thesis explores the application of a neural network approach to cell tower localization using crowdsourced measurements. The deployment of cell tower infrastructure has been increasing exponentially in recent times as it is a crucial element of mobile communications. LÄS MER

  4. 3. Machine Learning-based MIMO Indoor Positioning

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Qiyi Chen; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. LÄS MER

  5. 4. Formation Control of UAVs for Positioning and Tracking of a Moving Target

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Robert Carsk; Alexander Jeremic; [2023]
    Nyckelord :Autonomous; UAVs; Drones; Sensor Fusion; MPC; Filter; KF; EKF; Signal; Tracking; Formation; Controller; Control; MWSN; Optimal Control Problem; Optimization; Seeker Drone; Target Drone; Quadcopter Model; Simulation;

    Sammanfattning : The potential of Unmanned Aerial Vehicles (UAVs) for surveillance and military applications is significant — with continued technical advances in the field. The number of incidents where UAVs have intruded into unauthorized areas has increased in recent years and armed drones are commonly used in modern warfare. LÄS MER

  7. 5. Real-time remote processing enabled by high speed Ethernet

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Dumitra Iancu; Lina Tinnerberg; [2023]
    Nyckelord :Large Intelligent Surfaces; Deep Neural Networks; FPGA; VHDL; Ethernet; Technology and Engineering;

    Sammanfattning : A growing trend within the technologies acting as enablers for 6g, such as Massive MIMO and Large Intelligence Surfaces, is benefiting from both the communication and the positioning aspects that they can provide. As these kinds of systems are employing a large number of arrays which provide high amounts of data, a distributed hardware approach having near-antenna processing is explored in this work. LÄS MER
